Cicada Invasion: A Once-in-a-Lifetime Phenomenon
Spring 2024: A Chorus of Cicadas
In a remarkable natural spectacle, the year 2024 will witness the emergence of an astounding number of cicadas across the United States. Two distinct broods, Brood XIX and Brood XIII, will simultaneously emerge from their underground abodes after spending an incredible 17 and 13 years, respectively, in subterranean seclusion. This extraordinary event, occurring for the first time in 221 years, will captivate entomologists and nature enthusiasts alike.
Geographic Distribution of the Cicada Emergence
The impending cicada emergence will span 17 states, creating a symphony of buzzing and clicking sounds across the nation. States like Illinois and Indiana will have the unique experience of hosting both Brood XIX and Brood XIII, while other states will witness the emergence of either brood. This widespread distribution promises an unforgettable natural phenomenon that will leave a lasting impression.
The Rarity of Simultaneous Emergence
The simultaneous emergence of Brood XIX and Brood XIII is a rare occurrence, made even more remarkable by their geographical overlap. Typically, different broods emerge every five to six years, maintaining a separation in their emergence patterns. However, this year’s event marks a departure from the norm, with two broods coinciding in their emergence, creating an unprecedented spectacle.
Brood XIX and Brood XIII: A Closer Look
Brood XIX, last seen in 2011, boasts the largest geographic extent among periodical cicada broods. Its range stretches along the East Coast from Maryland to Georgia and extends westward into the Midwest, encompassing states like Iowa and Oklahoma. Brood XIII, on the other hand, will emerge in Iowa, Illinois, Indiana, Wisconsin, and possibly Michigan, adding to the widespread nature of this extraordinary event.
Abundance and Timing of the Cicada Emergence
The sheer number of cicadas expected to emerge this year is staggering, exceeding a trillion individuals. This massive emergence is akin to the size of Delaware, covering approximately 1.5 million acres. The emergence is anticipated to commence in mid-May and culminate in June, painting the landscape with a vibrant tapestry of buzzing insects.
The Sensory Impact of Cicadas
The emergence of cicadas is not only a visual spectacle but also an auditory one. These insects produce a distinctive clicking and buzzing sound that can reach deafening levels, reaching up to 105 decibels. This cacophony has been likened to a “singles bar gone horribly, horribly wrong,” as described by entomologist John Cooley of the University of Connecticut.
The Harmless Nature of Cicadas
Despite their formidable numbers and noisy presence, cicadas pose no threat to humans or animals. They are not poisonous, do not bite or sting, and are generally harmless. However, their exoskeletons can be difficult for some animals to digest, potentially causing stomach upset. Consulting a veterinarian is recommended if concerns arise about a pet’s reaction to cicadas.
Conclusion: A Unique Natural Event
The cicada emergence of 2024 promises to be an extraordinary natural event, a symphony of sound and movement that will captivate and amaze. While some may dread their arrival, these insects play a vital role in the ecosystem, contributing to the decomposition of organic matter and serving as a food source for various animals. Embrace the spectacle, appreciate the intricate workings of nature, and revel in the once-in-a-lifetime opportunity to witness this awe-inspiring phenomenon.
